Abstract/OtherAbstract:
Following the addition of EGF or ionomycin to A431 cells, protease activity mediates the cleavage of the EGF receptor producing a 60 kDa fragment that includes the intracellular domain (ICD). This fragment is located in both membrane and nuclear fractions. Based on sensitivity to chemical inhibitors and overexpression of cDNAs, the rhomboid intramembrane proteases, not γ-secretase proteases, are identified as responsible for the cleavage event. Agonist-initiated cleavage occurs slowly over 3-24 hrs. Inhibition of calpain protease activity significantly increased the detectable level of ICD fragment.
